Long exposure/interval shooting

I have recently been trying to do long exposure shots coupled with the interval shooting mode to get shots to make a composite star trail photo, I have been trying for an exposure time of 20-30 seconds, and the interval shooting at interval 2 seconds for multiple shots. I have been finding that most of the time the camera will only expose once and then show as interval shooting completed. I played around with different exposure times, and anything over 1 second exposure will cut down the number of times i've set it to repeat.

Can anyone tell me where I'm going wrong on the settings?

I think the interval must contain enough time for the exposure also. So I think a 30 second exposure that you want to go off every 2 seconds needs a 32 second interval or longer.

If your exposure is 30 seconds then you'll need a roughly 33 second interval. Give the camera a few seconds to process and save the data before the next shot.

At least you know you have a brain - I have been going in circles today so perhaps I lost the power steering pump on mine.

You can also just set continuous shooting, and let the camera body just go and take shots back to back until you stop it.

Remember to disable background subtract if you want short intervals between long exposures.

Your profile says K20D and I'm not sure if you can. See what the [Custom Setting] menu allows you to do for [17. Slow Shutter Speed NR].

I shoot in "Hi Continuous" with a wired remote that has a toggle switch.
This StarStaX - www.starstax.net works great for post processing.
Just limit your exposure time below the dark-frame subtraction threshold.

Cheers.
